Influence Of Various Antibacterial Preparations On Rate And Efficiency Of Gain By Young Pigs (1973), G L. Allee, D A. Schoneweis
Influence Of Various Antibacterial Preparations On Rate And Efficiency Of Gain By Young Pigs (1973), G L. Allee, D A. Schoneweis
Kansas Agricultural Experiment Station Research Reports
Two trials involving 128 pigs were conducted to study the effects of antibacterial preparations on rate and efficiency of gain by young pigs. In both trials, the antibacterial preparations increased rate of gain. In trial I, there were no differences in performance of pigs fed ASP-250, Mecadox, or TNA-290. In the second trial, pigs fed Mecadox gained faster than pigs fed ASP-250, Furox or Neo-Terramycin. Pigs fed diets supplemented with the various antibacterial preparations utilized feed more efficiently than those fed the nonmedicated basal diet.; Swine Day, Manhattan, KS, November, 1973

Pigs farrowed in May, 1972, were the first born in the select and control lines. Performances of animals in the two lines were essentially the same. However, ham firmness and color differed significantly (P<0.0l) between lines, with those in the select line firmer and darker than those from the control line.; Swine Day, Manhattan, KS, November, 1973
Efficacy Of Virginiamycin As A Prophylactic Drug To Prevent Swine Dysentery (1973), D A. Schoneweis, G A. Kennedy
Efficacy Of Virginiamycin As A Prophylactic Drug To Prevent Swine Dysentery (1973), D A. Schoneweis, G A. Kennedy
Kansas Agricultural Experiment Station Research Reports
Forty-eight feeder pigs were used in an experiment to determine Virginiamycin's effectiveness in preventing swine dysentery. Thirteen of 24 controls and one of 24 that received the antibiotic at either 25 or 50 grams per ton of feed died of swine dysentery or complications. Feed conversion ratio was markedly improved by the antibiotic. Virginiamycin was judged effective in preventing clinical cases of swine dysentery, but it has not been cleared for use in swine. Swine dysentery, also known as bloody dysentery, vibrionic dysentery, bloody scours, or black scours, is a infectious, enteric disease of swine. It is serious in many …
Effects Of Supplemental Lysine, Methionine, And Threonine On Weanling Pigs Fed A Low-Protein Milo-Soybean Meal Diet (1973), G L. Allee
Kansas Agricultural Experiment Station Research Reports
Three trials involving 331 weanling pigs (5 to 7 weeks old and weighing 20 to 33 pounds) were conducted to determine the effects of supplementing low-protein starter diets with crystalline amino aqids. In trials I and II, milo-soybean meal diets containing 12, 14, or 16% protein were supplemented so each contained the same quantity of lysine as an 18% protein, milo-soybean meal diet. Weight gain and feed efficiency of pigs fed the 16% protein lysine-supplemented diet was equivalent to that of pigs fed the 18% protein milo-soybean meal diet. Trial III evaluated 14, 16, 18, and 20% protein milo-soybean meal …
Effects Of Endosperm Type On Nutritional Value Of Sorghum Grain For Swine (1973), G L. Allee, K Smith
Effects Of Endosperm Type On Nutritional Value Of Sorghum Grain For Swine (1973), G L. Allee, K Smith
Kansas Agricultural Experiment Station Research Reports
Two feeding trials, a digestion trial, and a preference trial were conducted to evaluate the effects of endosperm type on the nutritional value of sorghum grain in swine diets. Endosperm types evaluated were: (1) white endosperm--red seed coat;(2) Heterozygous yellow endosperm--bronze seed coat; (3) homozygous yellow endosperm--yellow seed coat. In trial I, 63 pigs averaging 47 pounds were used in a 28-day experiment. Performance of pigs in trial I was not influenced by endosperm type. A digestion study using 51 pound pigs showed endosperm type making no significant difference in protein digestibility or nitrogen retention. Trial II involved 81 finishing …
Influence Of Feeding Frequency On Performance And Nitrogen Metabolism In Gestating Swine (1973), G L. Allee
Influence Of Feeding Frequency On Performance And Nitrogen Metabolism In Gestating Swine (1973), G L. Allee
Kansas Agricultural Experiment Station Research Reports
The influence of feeding frequency on performance and nitrogen metabolism in gestating swine was studied by feeding 4 pounds daily, 8 pounds every other day, or 12 pounds every third day. All animals were maintained in dry lots with portable housing and were fed a 12%-protein, corn-soybean meal diet in individual feeding stalls. Three successive 6 day collection studies were conducted with 6 gilts. Nitrogen digestibility was not influenced by feeding frequency. However, nitrogen retention decreased as intervals between feeding increased. Gilts fed 4 pounds daily retained more nitrogen than those fed 8 pounds every other day, while those fed …
Feed Flavors In Swine Starter Rations (1973), Robert H. Hines
Feed Flavors In Swine Starter Rations (1973), Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Nursing litters given a choice of flavored or unflavored diets responded by consuming more flavored diet. Pre-weaning feeding did alter the preference patterns of the post-weaned pigs. Pigs fed only basal ration as creep exhibited a varied preference pattern during the post-weaning preference trial. Pigs with access to flavored diet during the creep period exhibited a continued preference for the flavored diet during the post-weaning phase. Average daily feed intake, average daily gain, and the feed/gain ratios were similar for post-weaned pigs offered only flavored or control diet regardless of the pre-weaning treatment.; Swine Day, Manhattan, KS, November, 1973
Lysine Supplementation Of Low-Protein Diets For Finishing Pigs (1973), G L. Allee
Lysine Supplementation Of Low-Protein Diets For Finishing Pigs (1973), G L. Allee
Kansas Agricultural Experiment Station Research Reports
Four experiments involving 311 finishing pigs (112 to 220 pounds) were conducted to determine the minimum level of soybean meal necessary to supply all essential amino acids except lysine that are deficient in milo or corn and to determine the influence of lysine supplementation of low protein diets for finishing pigs. The results of three trials using milo as the grain source demonstrated that pigs fed milo supplemented with 7.5% soybean meal and lysine gained at the same rate and were just as efficient in feed utilization as pigs fed milo supplemented with 15% soybean meal. Carcass composition as measured …
Limiting Amino Acids In Milo For The Growing Pig (1973), T E. Eckert, G L. Allee
Limiting Amino Acids In Milo For The Growing Pig (1973), T E. Eckert, G L. Allee
Kansas Agricultural Experiment Station Research Reports
Three growth trials and two nitrogen retention trials were conducted with 118 growing pigs to determine the limiting amino acids in milo. Lysine supplementation of the basal milo diet markedly improved daily gain, feed efficiency, and nitrogen retention. Adding threonine to diets containing supplemental lysine or lysine and methionine increased daily gain and improved feed efficiency. Similarly nitrogen retention was increased by adding threonine to the basal milo diet supplemented with lysine. Supplementing the basal milo diet with methionine in the presence of lysine gave no beneficial response in two trials and markedly depressed growth in a third. Supplementing with …
Evaluation Of A Protective Material To Prevent Abrasions And Infections Of Joints In Baby Pigs (1973), D A. Schoneweis
Evaluation Of A Protective Material To Prevent Abrasions And Infections Of Joints In Baby Pigs (1973), D A. Schoneweis
Kansas Agricultural Experiment Station Research Reports
Streptococcal and staphylococcal infections increase with increases in central farrowing housing and cause serious losses in young pigs. The baby pig may be affected in many ways, such as growths on the heart valves; pneumonia, and peritonitis; however, infected joints are the most serious problem in many herds. The pigs develop enlarged, crippling joints. Many die and others are stunted. Tentative diagnoses often are erysipelas; however, culture of the joints usually reveals that a strept and/or a staph is involved.; Swine Day, Manhattan, KS, November, 1973
Influence Of Diet Lysine Level On Performance Of Finishing Barrows And Gilts (1973), K C. Ferrell, G L. Allee, B A. Koch, Robert H. Hines
Influence Of Diet Lysine Level On Performance Of Finishing Barrows And Gilts (1973), K C. Ferrell, G L. Allee, B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
One hundred eighteen barrows and gilts were used to evaluate adding lysine to a 11.2% crude protein, milo-soybean meal ration. Rate of gain was significantly improved (P<.05) in both barrows and gilts receiving the higher dietary levels of lysine, but not feed efficiency. Loin-eye area of barrows receiving three levels of lysine was not affected, but loin-eye area of gilts was significantly improved by the addition of lysine to the diet. Carcass length, backfat thickness and ham and loin percentage were not improved in either barrows or gilts. Rate of gain, feed efficiency, and carcass parameters did not differ significantly for pigs fed .65 or .80% lysine.; Swine Day, Manhattan, KS, November, 1973

Coffee Grounds In Swine Rations (1973), T F. Balogun, B A. Koch
Kansas Agricultural Experiment Station Research Reports
As little as 10% of coffee grounds depressed the feed intake and growth rate of growing pigs and finishing pigs. Apparently, reduced growth rate resulted from lack of palatability rather than any toxic factor in the coffee grounds.; Swine Day, Manhattan, KS, November, 1973
